Instead of having 5 or 6 classes all semester long, you might have just 1 or 2 classes at a time, but they last a shorter amount of time. So, you might go to that same class 4 or 5 times a week, but only from Jan. - 2nd week of February - something like that. They cover the same amount of semester hours, but you are more focused at one time on only a couple of classes. If you look around enough on their regular .edu web site, you can find how classes were scheduled for P1, P2, P3 this year.
